Waterproof bag means

ABSTRACT

A bag means comprising a main body ( 1 ) made of a mesh material as a whole except an opening portion thereof and a completely waterproofed inner bag ( 3 ) to be put in the main body ( 1 ) detachably.

BACKGROUND OF THE INVENTION

[0001] Field of the Invention

[0002] This invention relates to a waterproof bag means and in particular to waterproof bags or pouches for campers, mountain climber, etc., such as rucksacks or backpacks, knapsacks and other types of bags for outdoor activities.

[0003] Ideally, a combination of three functional properties, i.e., lightness in weight, sufficient waterproofness and also proper air-permeability, are essential for such a bag means, however, it has been impossible to combine these mutually inconsistent properties in a bag. If one of these properties is improved, the remainder would be deteriorated. For example, waterproofness not only affects lightness in weight and air-permeability but also causes the following problems which have not been solved yet:

[0004] (1) a highly waterproofed material increases weight and production cost thereof;

[0005] (2) waterproofness of materials to be used for a bag means is not sufficiently improved compared with that of cloths, while durability is lower;

[0006] (3) when a bag means is exposed to heavy rain, etc., water tends to soak thereinto even if the bag is highly waterproofed;

[0007] (4) the thus soaked water is not easily drained dry; and

[0008] (5) a seam sealing treatment of bag means further increases the production cost.

SUMMARY OF THE INVENTION

[0009] According to the present invention, there is provided completely waterproofed bag means comprising a main body made of a mesh material as a whole except an opening portion thereof and a completely waterproofed inner bag to be put in the main body detachably.

[0010] A smooth outer cover may be detachably put on the outside of the main body.

BRIEF DESCRIPTION OF THE DRAWINGS

[0011]FIG. 1 is an exploded perspective view of a rucksack according to the present invention.

[0012]FIG. 2 is an exploded perspective view of a pouch according to the present invention.

[0013]FIG. 3 is an exploded perspective view of a handbag according to the present invention.

DETAILED DESCRIPTION OF THE INVENTION

[0014] There may be used any kind of conventional materials as a mesh material for the present bag means, although less water-absorbing one is preferable.

[0015] An inner bag to be put in a main body contributes to weight-saving of the present bag means as a whole, because only waterproofness might be considered rather regardless of durability thereof.

[0016] The present bag means makes it possible to keep various kinds of things independently under a dry condition in the inner bag and an air-permeable condition between the mesh main body and the inner bag, respectively. Due to the above mentioned structure of the present invention, both of improved waterproofness and air-permeability can be secured simultaneously. Similarly, due to this structure, weight of the bag means as a whole can be saved.

[0017] As the inner bag prevents soaking from water from outside environment almost completely, the bag can be used continuously without draining.

[0018] Further, things put in the space between the mesh main body and the inner bag can be checked easily from outside and, in addition, willingly dried, if necessary.

[0019] An outer cover may also be put on the mesh main body in bush, etc. so as to protect the mesh.

EMBODIMENTS

[0020] Referring now to the drawings, the present invention will be detailed.

[0021]FIG. 1 is a perspective view of a rucksack according to the present invention, in which numerals 1, 2 and 3 designate a main body, a lid portion and an inner bag, respectively, while numerals 4 and 5 designate catch.

[0022] Except the lid portion 2 for getting things in and out, the main body 1 is made of a nylon mesh material. The inner bag 3 is made of waterproofed nylon taffeta for rainwear, while seam thereof is sealed by means of seam tape to enhance waterproofness.

[0023] An opening portion of the inner bag 3 is folded to seal the bag 3 by means of a seamed nylon tack 6.

[0024] The main body 1 and an upper portion of the inner bag 3 are joined by means of loop clutches 4 and hooks 5 so as to fit the bag 3 inside of the main body 1 firmly.

[0025] The remainder structure of the present bag means is essentially similar to conventional rucksacks.

[0026]FIG. 2 is a perspective view of a waist pouch. Basic structure of a main body is the same as that of the rucksack shown in FIG. 1.

[0027] An inner bag 3 is made of the same material used for the above mentioned rucksack, which opening portion is closed tight by means of a closing string 7, then folded back and finally tightened by means of a magic taped belt 8.

[0028] The inner bag 3 is fit inside of the main body 1 firmly by means of hooks 5 similarly as described above.

[0029] Numeral 9 designates a nylon outer cover. The outer cover 9 is formed to just fit on the main body so as to cover the mesh completely, thereby hooks 10 being used to fix the cover 9 on the body 1.

[0030]FIG. 3 is a perspective view of a handbag. Basic structure of the handbag is the same as that of the rucksack shown in FIG. 1, except that the lid portion is omitted and double top handles are formed.

[0031] An inner bag 3 is made of the same material as described above and formed as a box shape to fit into a main body 1, while an opening portion thereof is closed tightly by means of seamed nylon tacks 11 and a slide fastener 12.

[0032] The inner body 3 is fixed inside of the main body 1 by means of hooks 4. 

What is claimed is:
 1. A completely waterproofed bag means comprising a main body made of a mesh material as a whole except an opening portion thereof and a completely waterproofed inner bag to be put in the main body detachably.
 2. Bag means claimed in claim 1 to which a smooth-surface outer cover is detachably put outside of a main body to cover at least a mesh portion thereof.
